Title Postdoctoral Fellow

School Harvard T.H. Chan School of Public Health

Department/Area Department of Immunology and Infectious Diseases

Position Description

The Le Pen Lab at the Harvard T.H. Chan School of Public Health ( HSPH ) is seeking a Postdoctoral Fellow to join our research on innate immunity to RNA viruses. The position is funded by the NIH Directorʼs New Innovator Award (DP2), Next-Generation Interferons: Mapping and Engineering Antiviral Function ( NIAID , 2026–2031). (https://hsph.harvard.edu/research/le-pen-lab/).

Our Research

We seek to explain a fundamental paradox in human disease: why common viral infections cause little harm in most individuals yet lead to life-threatening or chronic disease in others. We investigate the cell-intrinsic mechanisms of innate immunity that enable cells to detect viruses, limit infection, and resolve immune activation once the pathogen has been cleared.

We focus on long-lived, irreplaceable cell types such as neurons and pancreatic β cells, which, unlike epithelial cells, must survive infection while keeping their specialized functions. Two questions organize the work:

• How do infected cells control viral replication while preserving the functions required for normal tissue function?

• How are antiviral and inflammatory responses actively shut down once a threat has been eliminated?

The DP2 project

Interferon fails in opposite directions: too weak, and ordinary viruses become lethal; too strong or too prolonged, and it drives inflammatory and autoimmune diseases. The project attempts to uncouple the wanted and the undesired effects of interferon, combining human genetics, functional screening and cell biology.

The fellow will take on a substantial part of this program, with scope to develop a research direction that is original but fits the aims of the award and the priorities of the group.

The environment

• The DP2 runs until 2031, giving the project a long funding horizon to start from, and we expect it to bring in further grants as it develops.

• The lab was established in December 2024, with dedicated space, BSL -2+ and BSL -3 access, and exceptional institutional cores and scientific environment on the Harvard medical campus in Longwood. The successful candidate will help shape its direction and culture.

• We sit in the Department of Immunology and Infectious Diseases at Harvard Chan, with a secondary affiliation with the Harvard Medical School Department of Microbiology and membership of the Harvard Program in Virology. Fellows are supported in attending conferences, giving talks, writing proposals and mentoring.

Basic Qualifications

• Ph.D. in a relevant field (immunology, virology, genetics, molecular biology, structural biology or related).

• Strong skills in experimental design, data analysis, and oral and written communication.

• Proficiency in standard cell culture and molecular biology techniques.

• Highly creative, able to work independently and collaboratively.

Additional Qualifications

• Proven success in publishing research papers.

• Expertise in interferon biology, innate immunity or virology is a plus.

• Expertise in structural biology is a plus.

• Expertise in bioinformatics is a plus.
